Kusukela ekuqaleni kuka-2020, ubhubhane olusha lomqhele luhlasele umhlaba wonke futhi lube nomthelela embonini ye-PCB yomhlaba wonke.I-China ihlaziya idatha yevolumu yokuthekelisa yanyanga zonke ye-PCB yase-China ekhishwe yi-General Administration of Customs.Kusukela ngoMashi kuya kuNovemba 2020, inani lokuthunyelwa kwe-PCB yaseChina lafinyelela kumasethi ayizigidi eziyizinkulungwane ezingama-28, okuwukukhula konyaka ngo-10.20%, okuyirekhodi eliphezulu kule minyaka eyishumi edlule.

Phakathi kwazo, kusukela ngoMashi kuya ku-Ephreli 2020, ukuthunyelwa kwe-PCB yaseChina kukhuphuke kakhulu, kwakhuphuka ngo-13.06% kanye no-21.56% unyaka nonyaka.Izizathu zokuhlaziya: ngaphansi kwethonya lobhubhane ekuqaleni kuka-2020, izinga lokusebenza kwamafekthri e-PCB yase-China ezweni lase-China, ukuthunyelwa kabusha ngemva kokuqaliswa kabusha komsebenzi, kanye nokugcinwa kabusha kwezimboni zaphesheya kwezilwandle .

Kusukela ngoJulayi kuya kuNovemba 2020, ukuthunyelwa kwe-PCB yaseChina kukhuphuke kakhulu unyaka nonyaka, ikakhulukazi ngo-Okthoba, okukhuphuke ngo-35.79% unyaka nonyaka.Lokhu kungahle kube ngenxa yokutholwa kwezimboni ezansi nomfula kanye nesidingo esikhulayo samafekthri e-PCB aphesheya kwezilwandle.Ngaphansi kwalolu bhubhane, umthamo wokunikezela wamafekthri we-PCB waphesheya awuzinzile.Izinkampani zase-Mainland Chinese zenza ama-oda oDlulisela phesheya kwezilwandle.

Ngokusho kwedatha ye-Prismark, kusukela ngo-2016 kuya ku-2021, izinga lokukhula kwenani lokukhishwa kwengxenye ngayinye yemboni ye-PCB yaseShayina liphezulu kunesilinganiso somhlaba wonke, ikakhulukazi kokuqukethwe kobuchwepheshe obuphezulu njengamabhodi aphezulu, amabhodi we-HDI, amabhodi aguquguqukayo. kanye nama-substrates wokupakisha.PCB.Thatha ama-substrates okupakisha njengesibonelo.Kusukela ngo-2016 kuya ku-2021, inani lokukhishwa kwe-substrate yokupakisha yezwe lami kulindeleke ukuthi likhule ngezinga lokukhula elihlanganisiwe lonyaka cishe elingu-3.55%, kuyilapho isilinganiso somhlaba wonke singu-0.14 kuphela%.Umkhuba wokudluliswa kwezimboni usobala.Ubhubhane kulindeleke ukuthi lusheshise ukudluliswa kwemboni ye-PCB e-China, futhi ukudluliselwa Kuyinqubo eqhubekayo.
